Hi,
that depends. Which HP 5130-48G-4SFP+ are we talking about? Is it the
"HPE 5130-48G-POE+-4SFP+ EI (JG934A)"
or the
"HPE 5130-48G-POE+ 4SFP+ HI (JH324A)"
because there is quite a difference.
Anyways I'm guessing the former, the EI model. That one has a 370W PoE budget. So an equal distribution of Power pr port gives 370/48 = 7.7 Watts pr port.
or if you talk full PoE+ (which is rated to 30W), you have enough power for 370/30 = 12 ports maximum.
Normal PoE rating is 15.4Watts which gives 24 ports.
You can tell your power-budget in detail by issuing the command.

Here is an example from one of our switches running 3113P05 (shipped software)

So, if your maximum usage is 15 APs at 13Watts, you should be well below the limit.
NB: If you do have the HI-model, the PoE budget is depending on which power supply units you are using.
it has a 720W option and a 1100W option (with 2 slots) which actually gives you the possibility for PoE+ on all 48 Ports.
